Error: rocket failed: failed to extract configuration if using "localhost" as a host on the server

[perk11]

When running cargo run -p deepseek-ocr-server -- --host localhost --port 9343, I'm getting the following output:

cargo run -p deepseek-ocr-server -- --host localhost --port 9343
    Finished `dev` profile [unoptimized + debuginfo] target(s) in 0.12s
     Running `target/debug/deepseek-ocr-server --host localhost --port 9343`
Server ready on localhost:9343 (deepseek-ocr)
Error: rocket failed: failed to extract configuration

It works fine if using 0.0.0.0 or 127.0.0.1, but an error message could be improved

I will try to improve error message in future release, thanks for feedback.
